And when I execute it on Windows 7 with Windows 2000 compatible mode, it also crashes same reason.

I analyzed it , the program calls RegisterClass with illegal WNDCLASS strucutre.

The style value 0xfffe080b.

I think you forgot initialize style value initialize with 0.

I think The correct value is 0x0002080b.

When I change it, it works fine.

jv16

Do you mean the program crashes with this error right when you start it? Or when you try to use some tool?

Hi.

When I click left pane Icon It calls RegisterClass "TPowerToolsHintWindow" with illegal style(0xfffe080b) WNDCLASS structure and raise exception 0x0EEDFADE.

You can see it on Windows 7 with Windows 2000 compatible Mode, and crashes with same reason on Win 7.

Here is stack calls.
